STAPLE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 731,630, dated June 23,1903.

Applicationfiled March 1, 1902.

To all whom it may concern.-

Be it known that we, EDWARD A. SUVER- KROP and ROBERT COATES, residingin the city of Philadelphia, county of Philadelphia,

and State of Pennsylvania, have jointly invented certain new andusefulImprovements in Staple-Machines,of which the following is aspecification.

i This invention relates to machines for forming and setting staples, asin the manufacture of paper boxes and leather goods, for example. Itschief objects are to provide in a single machine mechanism for cuttingvariously-shaped blanks, forming staples of various proportionstherefrom suitable for va-' rious uses and settingthe staples so formedall in a continuous operation. The means employed to accomplish theseobjects permit the use of a metallic ribbon of uniform width,

from which staplesof various proportions can be formed. No waste ofmaterial is entailed, as no scrap is formed, all of the material beingincorporated in the staples, which have a peculiar form, lendingstrength to the at- The mechanism of the staples at will.

The further objects and characteristic features of theimprovements willmore fully appear in the following description, taken in connection withthe accompanying drawings in illustration ofthe invention, of which-Figure 1 is a top plan view. Fig. 2 is a side elevation. Fig. 3 is afront elevation. Fig. 4. is a sectional View in illustration of themovable head, taken on the line 4 4 of Fig. 5. Fig. 5 is a sectionalviewtaken on the line 5 5 of Fig. 4. Fig. 6 is a sectional View taken on theline 6 6 of Fig. 4. Fig. 7 is a sectional viewshowing details of thestriking mechanism.

As illustrated in thedrawings, the frame 1 has a head 2, which guides avertically-recip- Serial No. 96,199. (No model.)

rocating bar 3, operated by a lever 4, the lever being fulcrumed uponthe frame-strut 5 and pivotally connected with the bar-head 6. The bar 3has a die 7 movably connected therewith by means of a pin 8', which isfixed .in the die and movably seated in the slot 9 of the bar. A pin 10,pressed down by a spring 11, bears upon the pin 8 and thrusts the die .7downwardly; but when the die is stopped in the downward movement of therod 3 the striking or forming pin 3 has a further movement through thedie, which is permitted by the play of the pin 8 in the slot 9 and thecompression of the spring 11, caused by stopping the pin 10 in itsdownward movement with the rod 3. The die 7 has a shearing edge 7, whichcoacts with a shear 12, supported by the frame-arm 13, a guide 14:controlling the movement of a ribbon of metal 15, which is fed to theshears and out thereby into diamond-shaped blanks 16. The blank, whichis cut by the descending die 7, is placed thereby upon one of a seriesof dies 17, each having a perforation 18, into which the striking-pin3is adapted to force a blank againsta pin 19,which plays in theperforation. {Astaple or rivet 20 is formed thereby and has the longpoints 20 and the short points 20", the former penetrating and bindingthe materials together, while the latter bite the surface andhold thehead thereto.

The several dies 17 are fixed in a ring or collar 21, which revolvesupon a bearing-head 22, having a peripheral channel 23, in which theinner ends of the several pins 19 move. The collar 21 is rotated bymeans of ratchetteeth 2-ithereon,whichareengagedbyaspringpressed pawl25, pivoted to a ring 26, loose on :the collar, the ring being pivotallyconnected with a link 27, having a pivotal connection 28with thereciprocating striking mechanism. By this mechanism the dies 17 aregiven a step-by-step motion, which carries them successively intoregistration with the die 7 and pin 3' and successively over theanvil orworkholder 29, a spring-pressed pawl 30, riding upon the polygonal ring31 on the collar, centering the dies. The head 22 is adapted toreciprocate in a guideway 32, supported by the frame, a spring 33,seated in the recess 10o the foot, and the foot being forced downward bythe arm 42, fixed to the rod 3, in the path of which arm the head islocated. The downward stroke of the rod 3, by which the die 7 is causedto strike one of the dies 17 and the arm 42 is caused to strike the head40, forces down the head 22 until the lowermost die 17 strikes thework-support 29 and at the same time forces down the foot38 and thecorresponding pin 19, which drives the staple seated in the perforation18 through the material held on the anvil. When the rod 3 rises, therespective springs 33 and 41 lift the head 22 and foot 38 to theirnormal the shears.

position, while the pawl 25, engaging with a ratchet-tooth 24, brings asucceeding die 17 under the striking-die 7 and a diametrically oppositedie 17 over the anvil 29.

The feed mechanism comprises a frame 44, having arms 45, which arerevolubly supported on the head 2, the position of the yoke and theangle at which the ribbon shall be fed being accurately determined bymeans of a gage 46, while the parts are held in the position to whichthey maybe adjusted by means of a set-screw 47, which passes through aslot 48. A reel 49, journaled at 50 upon the frame, carries the metallicribbon 15, which is fed over the shear 12, beneath the guide 14, by therollers 52 52, journaled in the frame, a positive action of the rollersbeing secured by means of the engaging gear-wheels 53 53. Aratchet-wheel 54, fixed to the roller 52, is engaged by a pawl 55, whichis pivoted on the rocking arm 56. The arm 56 is pivoted to one end of alink 57, the opposite end of which is pivotally connected with a bearingmovably fixed in a slot 58 of alever 59. The lever 59 has one endpivoted on the frame 44 and the opposite end pivoted to a link 60, whichhas a second pivotal connection with an arm 61, longitudinally fixed butrevolubly movable on the rod 3, the arm being guided in itsreciprocation by a rod 62 passing through it and fixed to the frame. Itwill be seen that by this mechanism the angle at which the blank isshorn from the metallic ribbon, and consequently the length of theprongs, may be varied by varying the position of the frame 44, andconsequently the angle at which the metallic ribbon is fed to It willalso be seen that by moving the connection of the link 57 with the lever59 the rate of feed and the proportions of the staple may be varied. Theangle at which the staple-blank is cut may also be varied by providingmeans for changing the position of the die-shear 7 and the shear 12.This may be done by providing a revoluble connection between the rod 3and the head 6 and employing a set-screw 6 for holding the die-shear 7in the position to which it may be adjusted, and for correspondinglychanging the lower sheara shear 14', revoluble in a seat 15, may beemployed and fixed in the position to which it may be adjusted by meansof a set-screw 16 passing through the shear-slot 17 and the seat 15.

It will now be seen that the oscillation of the lever 4, whichreciprocates the rod 3 upon the downward stroke, causes the shears 7'and 12 to cut from the tape or ribbon 15 the blank 16, and the die 7with its pin 3, aided by the die 17 and its pin or plunger 19, to formthe staple 20. The downward stroke, which forms the blank and staple inthe uppermost die 17, forces down the head 22 until the lowermost die 17strikes the material on the anvil 29, and the foot 38, driven down bythe arm 42, strikes the plunger 19, which sets the staple that is seatedin the perforation 18 and rivets it in the work supported by the anvil.Upon the upward stroke the pawl 25, engaging with a teeth 24, advancesthe ring or collar 21, bringing a succeeding die 17 under the die 7 anda succeeding die 17 over the anvil 29, while the springs 33 and 41elevate the head 22 and the foot 38, and coincidently with thisoperation the feeding mechanism connected with the rod 3 causes thefeed-rollers 52 52 to advance the tape sufficiently for the productionof a succeeding blank and staple. By adjusting the shears 7' and 14' orby adjusting the frame 44 the angle at which the tape or ribbon 15 isshorn may be varied, and by adjusting the connection of the link 57 withthe lever 59 the length of ribbon fed at each shearing operation may bevaried. Hence the diamond-shaped blank and the staple formed therefrommay readily be varied at will.

Having thus described our invention, we claiml 1.
